See the chart titled: Performance in images per second per $.

TPUv2 is has 1.27x-1.86x the images/s/$.

And the other chart titled: Cost to reach 75.7% top-1 accuracy.

Where TPUv2 costs 62.5% the reserved GPU instance and 42.6% the unreserved GPU cost.

Key takeaway from the article:

> While the V100s perform similarly fast, the higher price and slower convergence of the implementation results in a considerably higher cost-to-solution.
